AR Spanish American War Soldiers (lookup req)

Is there someone in Washington County who would be willing to do a lookup for me the next time you are at the Fayetteville Public Library?

The Grace Keith Genealogical Collection has a book titled "Arkansas' Spanish American War Soldiers"which lists info about the soldiers from Arkansas who fought in this war. I have already consulted the index, and am looking for information on the following soldier:

Don A. Gribble

There should be one or two lines which list his dates of enlistment, unit, and other information.
